MacBook m2芯片电脑安装哪个版本的Android studio
说明：Mac上选择Android studio需要选择带arm的版本。不然会安装不起来。
具体版本见前面“Android Studio安装”。
android studio默认安装路径Mac
- 本机安装地址为：
/Users/hh/Library/Application Support/Google/AndroidStudio2020.3
Android studio升级问题
-
AS启动之后，一般会有如下弹框，
image.png 如果不幸点了上面的Gradle升级弹框，没出问题则罢，出了问题大概率情况需要重新安装Android studio。
注意：重装AS前，最好清理掉如下3个位置：
1）AS安装目录
比如Mac上目录如下：
/Applications/Android Studio.app
2）AS下载的SDK目录
比如Mac目录如下（这是自定义目录，根据安装时目录具体找）：
/Users/hh/Documents/android/sdk
3）gradle所在目录
比如Mac上目录如下：
/Users/hh/.gradle
Gradle sync失败

2021-11-24 20:03:56,534 [2025237] ERROR - intellij.openapi.progress.Task - Module: 'app' platform 'android-29' not found.
处理：
缺少platform 'android-29'，从setting->sdk 中下载platform 'android-29'，重新同步。参考：

AS（Android Studio）显示工具栏步骤：
- 主要使用点击到回到上一页/下一页功能。
- 结论：
View -- Appearance -- Toolbar 打上勾就会显示了。
build.gradle配置
gradle清理缓存
- 强制清除gradle 缓存/Mac gradle清理缓存
Windows:
gradlew build --refresh-dependencies
Mac:
./gradlew build --refresh-dependencies
- Mac如果遇到如下问题：
zsh: no such file or directory: ./gradlew
处理：最简单的方式就是终端执行cd命令到gradlew下（每个Android工程都有该工具），然后再执行上述命令。

- 说明：如果targetSdkVersion设置31或以上，则需要适配Android 12，看资料可知需要将工程中AndroidManifest.xml所有exported的地方设置为true，包括引入的库也需要做适配（比如在app下的build.gradl做配置，具体见如下参考）。如果工程不对这个做要求，可以降低targetSdkVersion版本（低于31）即可。

Android Studio自带的JDK目录：

http://t.zoukankan.com/morlin-p-4647447.html
https://www.jb51.cc/mac/2923682.html说明：Android Studio自带的JDK没法用，只好额外安装JDK。
安装了JDK18：
java version "18.0.2.1" 2022-08-18
Java(TM) SE Runtime Environment (build 18.0.2.1+1-1)
Java HotSpot(TM) 64-Bit Server VM (build 18.0.2.1+1-1, mixed mode, sharing)
通过keytool命令：
keytool -list -v -keystore + keystore的绝对路径
能够拿到证书指纹，包括SHA1和SHA256，但是获取不到MD5.
解决：需要降低JDK版本，比如安装Java7就可以获取到MD5.
